Abstract: The addition of the title compounds 1 with methallyl Grignard reagent yielded the carbinols(2).Catalyzed by BF3·Et2O,the carbinols 2 can be converted to aromatic ether 3when the reaction was performed in lower alcohols which were used as the nucleophile.The conversion from 2 to 3 can be regarded as a substitution-cycloaromatization reaction in mechanism and proved to be a facile approach to the synthesis of this kind of compound(3).

Key words: β,β-1,3-Propylenedithio-α,β-unsaturated arylketones, Methallyl grignard reagent, Adducts, Substitution-cycloaromatization
